Just when you thought the poet was being original, it turns out this is another, legit, term for the ionosphere.

Oliver Heaviside, physicist and mathematician, proposed that a stratum existed in the atmosphere that caused wireless signals to bounce back to earth, and that this would account for why signals could travel very long distances over the horizon. Others confirmed its existence and dubbed it the Heaviside Layer. Scientists also confirmed that sunlight excited a region of the atmosphere known as the ionosphere, which accounted for the daytime distortion that had so plagued Marconi."
